Presentation
- 1. Department of Computer Science and Engineering SHRI PILLAPPA COLLEGE OF ENGINEERING PROJECT ON CANSim Tool to diagnose CAN Devices Guided & Coordinated by : Mr. Prof. Ranjan. B.E, M.Tech, Asst. Prof Presented by: Abhishek Singh (1PL12CS003) Amit Kumar Singh (1PL12CS004) Prashant Sharma (1PL12CS027)
- 3. INTRODUCTION The role of CANSim tool is to diagnose the program which is dumped in the CAN Hardware device. All CAN devices are Electronically Controlled i.e. they interact using electrical signals. This would reduce the cost of testing and Verification of the Hardware Devices to be installed in Automobiles. The need for Developing a tool for CAN Device diagnosis. Since every device to be installed on an Automobile cannot be crash tested directly we make use of an Application to do so without the use of Automobile.
- 4. EXISTING SYSTEM The existing system for CAN Hardware diagnosis is CANALYZER Pro by Vector International Pvt Ltd. This is a perfect tool for diagnosing the CAN Hardware devices but it also has following limitations : 1) Cost is too high for Each Copy of the tool. 2) The Source Code of the tool is Restricted from users.(Cant modify) 3) The features available in it are not 100% satisfying for the organization.
- 5. PROPOSED SYSTEM A Software tool which would provide the following Requirements : Open source tool. Cost Considerations. Ease of use for the user. Application Name : CANSim Project Type : Windows Form Application Programming Language Used : C# Programming Environment : .NET Additional Tools used : Vector-Hardware by Mathworks Matlabs Pvt Ltd Additional Libraries Imported : SourceGrid.dll
- 6. DESIGN CANSim 1 GUI Thread Background Worker Thread CANSim 2 GUI Thread Background Worker Thread The tool works in two modes : CANSim 1 When associated with another application. This tool will work as a part of that tool with a different GUI. CANSim 2 In this mode the tool runs as a standalone application. This tool works with a UI different to CAN Sim 1/
- 8. IMPLEMENTATION The key features/requirements specified by the organization are as follows : 1. Sending only selected Signals Sequentially 2. Shortcut Key assignment 3. Configuration Status 4. Clear all Contents 5. Cloning Feature 6. Send Signal Function
- 9. Step 1 : Check the Item Column to know which rows are selected by the user (Item is a Column with Checkbox) go to Step 2 Step 2 : Get the index values of the rows Checked/ Selected by the user go to Step 3 Step 3 : Get the time Interval t from the user go to Step 4 Step 4 : Select 1st signal to be transmitted (using the index values stored in an array) Send the signal Start the timer go to Step 5 Step 5 : Select next signal to be transmitted After time t Send Signal go to Step 6 Step 6 : If (the last signal sent is the last one in the sequence) Stop the timer. else go to Step 5 1.Sending only selected Signals Sequentially Functions Used Void button9_Click(object sender, EventArgs e) Void send() int check()
- 10. Step 1 : Identify the key pressed by the user via PreviewKeyDown Event. If(identified) go to Step 2 else Display Invalid Key in MessageBox Step 2 : Check whether any signal is assigned for the key pressed by the user. If (assigned) go to Step 3 else Do nothing Step 3 : Check whether two or more signals are assigned with same Alphabetical / Numerical Shortcut. If(assigned) Display Possibly assigned same shortcut for another signal in MessageBox. else go to Step 4 Step 4 : Check whether the data is valid or not , on the signal to be sent. If (valid) Send the Signal else Display Error Message in MessageBox. 2. Shortcut Key assignment Functions Used Int sc(); Byte Converter(); Void Grid_Signal_PreviewKeyDown(
- 11. Step 1 : Open Savefile Dialog and allow the user to enter the filename. If (filename is valid) go to step 2 else abort Step 2 : static extern long WritePrivateProfileString(string Section, string Key, string Value, string FilePath); /* static extern long GetPrivateProfileString(string Section, string Key, string Value, string FilePath); for Load */ Step 3 : Using the function in Step 2 Write the values in the filename.ini row by row in the following format. [SECTION 1] key1=value1 key2=value2 key3=value3 . . [SECTION 2] key1=value1 key2=value2 . . 3. Configuration Status (Save / Load ) Functions Used Void savecfg(); Void loadcfg(); Void WritePrivateProfileString(); Void GetPrivateProfileString();
- 12. Step 1 : Select first row go to step 2 Step 2 : Set the values of the following columns to their default/minimum values MsgID - Len - [B1-B8] - Interval - 10 Start - false(bool) Channel - Ch1 Key - If ( current_row -> Last_Row) stop else select next row goto Step2 4. Clear All Contents Functions Used Void button8_Click(object sender, EventArgs e)
- 13. Step 1 : Check for availability of empty row below the current position. if (found) Check whether the data in current position is valid or not. if (valid) write data in current position in the Empty row available. else Display Error Message else go to Step 2 Step 2 : Check for availability of empty row above the current position. (Starting from the top) if (found) Check whether the data in current position is valid or not. if (valid) write data in current position in the Empty row available. else Display Error Message else go to Step 3 Step 3 : Display All rows are filled in MessageBox . 5. Cloning Feature Functions Used Bool Checkbelow(); Bool Checkabove(); Void Write();
- 14. Step 1 : Check Whether the data to be transmitted is valid or not. (Make necessary corrections if required) Step 2 : Make data conversion (i.e. from decimal to Hex) Step 3 : Choose Appropriate channel as configured by user Step 4 : Create Send Event via XLClass.xl_event_collection Class Send information in sequence. 6. Send Signal Functions Used Void signal_Click(object sender, EventArgs e)
- 15. CONCLUSION Since CANSim is an Open Source product .It can be modified or enhanced as required. The Cost for Buying the Existing tool is saved. Can be used without the hardware for Testing by making use of Virtual Channels
